Is the population data specified anywhere for the 500 participants?

I shared this article to some colleagues which are married and have small children and they seem to disagree with these findings.

I tend to agree because home disturbances can be major in a household unless you isolate yourself totally.

On the other hand this could be great for single workers in the short term, unless we ignore the fact that most relationships occur due to high frequency meetings (aka work, study etc.).
